CREEPY TRUE TALES- Mummified at SEA?

A yacht was found adrift in Filipino waters in 2016. The captain, Manfred Fritz Bajorat had gone missing from 2009 to 2016 and so it was assumed by many that he was dead. No family nor friends had heard from him during this time.

No-one was sailing the ship and although the weather was poor the ship was seaworthy. But what was even stranger was that the captain was still aboard, still sitting at his desk, reaching for his phone – but his body was entirely mummified, which led the crew that had boarded his boat to believe that he had died some years before.

Once his body had been autopsied it was discovered that Bajorat had died only a week before. So why and how had his body mummified completely in just a week? and why hadn’t he contacted his family or friends during the years?
